What is the purpose of a Feedwater Gauge Glass?

• A. To measure steam pressure
• B. To visually indicate the water level in the boiler
• C. To regulate flow to the steam header
• D. To monitor exhaust gas temperature

Answer: (B)

The purpose of a Feedwater Gauge Glass is to visually indicate the water level in the boiler. This component is essential for the safe operation of the boiler system, as it enables operators to see the actual level of water inside the boiler. Maintaining the appropriate water level is crucial; if the level is too low, it can lead to overheating and damage to the boiler, while excessively high levels can also cause operational issues. The gauge glass provides immediate visual feedback, allowing for quick and informed decisions regarding water feed operations.

In contrast, measuring steam pressure is a different function performed by a pressure gauge, while regulating flow to the steam header involves control valves that are separate from level indication. Monitoring exhaust gas temperature is handled by temperature gauges, which serves a distinct purpose unrelated to water level detection in the boiler.
